Question:

The power module in your picture looks different from the manufacturers: https://www.tekonsha.com/product/118534_tow-harness-t-connector-assembly Has the power module changed recently?

No, the one on Tekonsha's website looks like an older picture or a different part. The ModuLite power module in our pictures for the T-One Vehicle Wiring Harness item # 118534 is what they look like.

The Tekonsha item # 118534 is confirmed to fit the 2017 Dodge Grand Caravan. I have linked an installation video below so you can see how to get it set up.

Hey, how did things go with the T-One wiring harness on your Grand Caravan? Did the ModuLite power module match what you expected once you got a closer look? Your update could make it easier for the next person comparing the different versions.
